Chlorinated Swimming Pools May Increase Cancer Risk: Study

Swimming in chlorinated pools may be associated with an increased risk of cancer, a small, new study contends.

Spanish researchers found evidence of DNA mutations in 49 healthy adults after they swam for 40 minutes in an indoor chlorinated pool, Agence France-Presse reported.

The findings, published in the journal Environmental Health Perspectives should not discourage people from using swimming pools, said Manolis Kogevinas, co-director of the Barcelona-based Center of Research in Environmental Epidemiology.
